Classification Of Textile Fibers - Sources Of Textile Fibre

Short Summary:

This video discusses the classification and essential properties of textile fibers. It explains that not all fibers are suitable for textile production; only those with sufficient strength, flexibility, elasticity, and durability (minimum 5mm length) can be spun into yarn or made into fabric. The video categorizes fibers into natural (vegetable, animal, mineral), man-made (synthetic), and regenerated fibers, providing examples like cotton, wool, silk, polyester, nylon, and rayon. Understanding these classifications and properties is crucial for textile manufacturing, influencing yarn and fabric quality. The video details essential fiber properties like length, strength, uniformity, spinnability, fineness, and durability.

Detailed Summary:

The video is structured into several sections:

1. Introduction to Textile Fibers: The video begins by establishing that not all fibers are suitable for textiles. Only fibers possessing sufficient strength, flexibility, elasticity, and a minimum length of 5mm can be used. Shorter fibers cannot be spun together. The example of corn silk (too weak) versus cotton (suitable) is used to illustrate this point.

2. Classification of Textile Fibers: This section details the three main categories of textile fibers:

Natural Fibers: These are further subdivided into:
- Vegetable Fibers: Examples include cotton (seed fiber), flax (bast fiber), hemp (bast fiber), jute (bast fiber), and coconut fiber (fruit/nut shell fiber). The source of the fiber within the plant is specified.
- Animal Fibers: These are protein-based fibers obtained from animals, such as wool (hair bulb), silk (secretions), and rabbit, camel, goat, and yak hair.
- Mineral Fibers: Asbestos is the only naturally occurring mineral fiber mentioned.
Man-Made Fibers (Synthetic): These are produced through chemical processes in laboratories and industrial settings via polymerization of monomers. Examples include polyester, nylon, acrylic, polypropylene, elastane, polyvinyl chloride, and polyurethane.
Regenerated Fibers: These are neither directly found in nature nor purely synthetic. They are produced by chemically processing natural materials. Examples include rayon, bamboo fibers, modal, and lyocell. The video also mentions non-cellulosic man-made fibers such as those derived from soy, corn, milk casein, and groundnut, as well as mineral, glass, ceramic, graphite, metallic (silver, gold, aluminum, steel), and rubber fibers.

3. Essential Properties of Textile Fibers: This section outlines crucial properties influencing a fiber's suitability for textile production:

Length and Breadth: A length-to-breadth ratio of over 1000:1 is typical.
Strength: Refers to tensile, bending, and bursting strength. Stronger fibers result in stronger yarns and fabrics.
Uniformity: Consistent thickness and length are vital for even yarns.
Spinnability: The ability to be twisted into yarn.
Fineness: Thinner fibers increase surface area for inter-fiber friction, leading to stronger yarns.
Luster: Natural luster enhances the value of fibers, particularly natural ones (silk is cited as an example).
Durability: Resistance to processing treatments and degradation from physical, chemical, and biological factors.
